For the first time in 15 years the Selaginella from our greenhouse
appeared to have strobili on the day of our seedless vascular plant
lab. At least that's what I thought. When I looked under the
dissecting scope, what I saw did not resemble a strobilus. Instead it
was a grapeshot-like cluster of oval swellings, green on the outside and
gray in the middle. Some had clear papillae protruding from the apical
end, almost looking like stigmas.
The leaves and growth habit of the plant look like Selaginella.
Can anyone shed some light on what I was looking at?
